Real-time detection method of internal environment temperature of electric vehicle motor controller

The invention discloses a real-time detection method of the internal environment temperature of an electric vehicle motor controller. According to the method, a temperature sensor and temperature measuring probes are used to detect the temperature of a circuit board and space in the motor controller respectively; when the motor controller enables a motor to run in a static working condition, the temperature difference between the temperature sensor and the temperature measuring probes is acquired; the motor controller runs in a rated working condition, and when the space temperature fluctuation is less than 1 DEG C, the temperature difference between the temperature sensor and the temperature measuring probes is recorded to acquire a temperature correction coefficient; the temperature correction coefficient is used to correct the real-time temperature detected by the temperature sensor; and finally the real-time environment temperature inside the motor controller is acquired through the temperature sensor to
